Why are smart contracts audits in Solidity so popular?

Solidity – the programming language for smart contracts

With 2.5+ million smart contracts, Solidity is the most popular programming language for smart contracts. Ethereum, Tron, Polygon, BNB, Optimism, and 30 other chains/protocols on EVM use Solidity. Naturally, most crypto audits are also done in Solidity. Solidity accounts for every other smart contract audit ever done.

Head of Smart Contracts Audits Department

“Solidity language has multiple use cases and it's ideally suitable for the growing DeFi ecosystem. There is a regular release of a new version of Solidity with embedded security fixes. However, it does not mean that the code remains free of bugs when new elements are added”

Hacken methodology is accepted by CoinGecko, CoinMarketCap, and Cer.live. We apply a four-stage approach to code review and analysis as it’s the most critical part. First, we run automatic tests to check all possible states of the contract and catch simple issues. Second, two separate auditors conduct independent line-to-line code reviews and analyses. Third, the lead auditor manually checks the parallel audits and performs an additional code review. Finally, auditors share the results and work out all disputable points. The smart contract audit by Hacken is so effective because it relies on several auditors to detect hidden weaknesses. We encourage our customers to go through our methodology before the audit and discuss any concerns and suggestions.

FAQ

  • Why are audits of smart contracts in Solidity so popular?

    Solidity is the most popular programming language for writing smart contracts in Ethereum. More than 2.5 million smart contracts are written in Solidity.

    Smart contracts written in solidity run on the Ethereum Virtual Machine (EVM). Ethereum, Tron, Polygon, BNB, Optimism, and 30 other chains and protocols, use this programming language. With Solidity, you can create contracts for voting, crowdfunding, blind auctions, and multi-signature wallets.

    Of 4,813 all smart contract audits, 2,456 audits reviewed the Solidity code. In other words, Solidity accounts for every other crypto audit.

  • What are the specifics of Solidity as a programing language?

    Solidity was designed for writing smart contracts. Solidity is so prevalent in crypto audits because it was specifically designed for smart contracts. Developers love Solidity because it integrates the most competitive features from C++, Python, and JavaScript.

    The programming language is best suited for decentralized apps thanks to its flexibility. Solidity is statically-typed, allowing it to handle complex user inputs. Its object-orientedness gives it a focus on a contract. Solidity is a high-level language making it more human-like. The programming language also supports inheritance, libraries, and complex user-defined types.

  • What is the primary objective of Solidity language?

    The primary objective of Solidity is the automation of transactions on the blockchain. It is used to create smart contracts on Ethereum and other blockchains.

  • How popular is Solidity in figures? What about cyber attacks?

    The total market cap of projects written in Solidity exceeds $1.8 trillion. The 24h trading volume is $338 billion. Contracts in Solidity are the most common targets for hacks, scams, and exploits. In 2020, 469 smart contracts in Solidity were hacked for $3 billion in damages.

  • What is the importance of a Solidity smart contracts audit?

    A manual check of your code by seasoned security specialists eliminates security flaws in smart contracts that may have appeared as a result of adding new functionalities or modifying some features. Thus, Solidity smart contracts audit is the instrument enabling better functionality and improved security.

  • Why do Solidity smart contracts become highly targeted by bad actors?

    In Web 3.0, the common rule is that the more popular a technology, the greater the risks of being hacked. Since Solidity is the most popular programming language for smart contracts, it is only natural that hackers target it the most. Thirty-two chains and protocols use Solidity. Because of its popularity, more than half of all smart contract hacks and exploits are connected to Solidity.

    Smart contract audits in Solidity make up 50 percent of all audits too. However, not all contracts have been audited and remain under higher threat. Thus, Solidity smart contracts audit is the way for projects to differentiate themselves from the myriad of Solidity-based projects for whom security is an empty word.
